Bananas actually grow on bushes
oh dear you people don't know a joke when you see one do you? LOL

They aren't bushes you idiot. They DO grow on trees.

Something growing on a tree doesn't make it a fruit. Berries grow on bushes and they're a fruit. Plus bananas do grow on trees. Whether or not something has seeds makes it a fruit. So pumpkins and squash are fruit. And bananas are fruit too.

bananas do grow on trees. and they are considered fruits.

It's not about tree vs bush, a fruit is the ripened reproductive body of a seed plant.
